Using Rails 3.1, where do you put your “page specific” JavaScript code?

Question

To my understanding, all of your JavaScript gets merged into 1 file. Rails does this by default when it adds //= require_tree . to the bottom of your appl

Answer 1

Move all your commom JS files to a sub-folder like 'app/assets/javascript/global' then in the application.js, modify the //= require_tree . line to //= require_tree ./global.

Now you are free to put your controller-specific JS on the 'app/assets/javascript/' root and they will not be included in compiled JS, being used just when you call them via = javascript_include_tag on your controller/view.
